Welcome aboard, sorry to disappoint but I have never seen any microwave display with a variable backlight.

3.4 - 3.7 kW = 3400 = 3700 Watts

I) empty the cabinet above the unit.
2) unplug the unit from the outlet in the cabinet
3) locate the two bolts near the front edge in the floor of the cabinet and remove them. the unit will tip down to the range below.
CAUTION SUPPORT THE UNIT WHILE TAKING OUT THE BOLTS OR THE UNIT WILL CRASH
4) Two people can then lift the unit from the support on the wall.

You rather have a bad turntable motor or a stripped turntable coupling.

1st: Dont listen to the so called gurus at FixYa. As the guru there was telling me that the frame was glued to the cabinet. If I would have followed his recommendation Id be buying new cabinets as well as a new mounting frame. FixYa should credit me my fee paid.
The solution: For the built-in cabinet AEG microwave oven, it is required to use the AEG mounting kit. The AEG mounting face frame uses for screws, one at each corner concealed by small black plastic caps that blend in perfectly with the contour of the mounting face frame. If you look closely towards the inside of each corner you'll see a very small slot in the cap that will allow you to put a small flat head screw driver into the slot to work the cap out. Once the four caps are removed use a phillips screw driver to remove the screws that fix the mounting face frame to the cabinet.

You did not note your Make and Model. As there are many different types, all I can give you are basic directions.
First make sure the Power Cord is UN-PLUGGED from the wall.

1. Remove the Top Vent Grille Cover. There are screws holding this on, either Three you can see (one on each side and one in the center), or Open the Door and look for screws at the top of the Frame that go Up Into the grille.
2. Look in cabinet above unit for screws that hold unit up. Usually two (one on each side, front), can be more. Remove.
3. Look where Top Vent Grille Cover was removed. There should be a Long Screw or Screw-Type Lock at each( top) corner. These hold the unit tight on the Wall-Mount Plate. Remove. You should have HELP at this point as you will slide the unit forward until it comes clear of the Support Arms.
GOOD LUCK!!
